No one is that foolish
I'll tell you what the problem is: I don't think you'll
find anybody to do the parallell "only trivial patches" tree.
They'll go crazy in a couple of weeks. Why? Because it's a
_damn_ hard problem. Where do you draw the line? What's
an acceptable patch? And if you get it wrong, people will
complain _very_ loudly, since by now you've "promised" them
a kernel that is better than the mainline.
